Colleague can't access Bes Web console on server from his PC. We all can. All on same network. All using same IE. Perhaps certificates?

hi guys

we have a Bes Express server set up on a Windows 2008 server. I can access the web admin console from my PC in Internet Explorer 9. My other colleague can from IE 11. When I get to the page, I see a 'Continue to this website' (not recommended).

The link is this:

One of my colleagues who is on the same network as me, is unable to access this page. He gets a page cannot be displayed from his IE 11 instead of what i see.

All firewalls are off on server and PC's. Could it be certificates related on his PC? Or even security update?

IS the BES site listed under Trusted Sites on the PCs where they can get in? And not on the PC of the user that cannot?
